Curt Adjustable Channel Mount

This CURT adjustable channel-style ball mount has a shank size of 2" x 2" and features two different trailer ball sizes to accommodate two different coupler sizes: 2" and 2 5/16". It also features an adjustable shank assembly with multiple mounting holes for varying ball heights. Each trailer ball can be raised to a maximum of 5 1/4" rise or lowered to a maximum of 6" drop, allowing you to make your trailer completely level in any towing situation. The channel-style design and dual-pin mounting system also provide a built-in anti-rattle feature to eliminate obnoxious chucking noises.
